Pond Boss Forums POND CONSTRUCTION Selecting a site Quarry Contest 2010

Maybe this is too simple (but simplification seems to be what you are encouraging with your last few hints!), but it seems to me that:

* lower water and less water exchange
* combined with less suspended sediment
* means the sediment is settling on the bottom
* and providing a rather nice rooting/growing environment for the Sago
* therefore the weed simply took off during the drought

Once the water level returned to normal:

* the exchange of water increased and
* there was more natural current within the lake so
* the sediments started moving around again (into suspension)
* there was deeper water over the thriving weed beds and
* less light was getting to those areas as a pure function of depth and also due to increased suspension of sediment (is turbidity the right term to use here?) so
* the Sago just couldn't grow well any longer

Do I get any points or is it time for the mercy killing angle with me??!!
